OBJECTIVE To explore the potential mechanism by which drug-containing serum of Dianxianqing granules (DXQ) inhibits microglial ferroptosis. METHODS Male SD rats were given normal saline and Dianxianqing granules solution via intragastric administration to prepare normal serum and DXQ, respectively. Mice microglia BV2 cells were collected and successfully transfected with a negative control small interfering RNA (si-NC), and then they were included in the si-NC group and cultured under normal conditions. Cells successfully transfected with small interfering RNA targeting glutathione peroxidase 4 (GPX4) (si-GPX4) were divided into the si-GPX4 group, the CsA group (treated with 1 μmol/L cyclosporine A), and the DXQ- L, DXQ-M and DXQ-H groups (treated with 5%, 7% and 10% DXQ, respectively). These groups were subsequently treated with their corresponding drug solutions and ferroptosis inducer Erastin (10 μmol/L). The intracellular levels of total iron ions, glutathione (GSH), reactive oxygen species (ROS), and the expression of mitochondrial superoxide were determined in each group after 48 h of treatment. Additionally, mitochondrial membrane potential, the opening degree of mitochondrial permeability transition pore (MPTP), and mRNA expressions of GPX4 and cyclophilin D (CypD) were detected. Furthermore, the expressions of ferroptosis-related proteins[GPX4, transferrin receptor 1 (TfR1) and ferritin heavy chain 1 (FTH1)], as well as MPTP-related proteins [adenine nucleotide translocator (ANT), cytochrome C (CytC), mitochondrial calcium uniporter (MCU) and CypD] were assessed. RESULTS Compared with si-NC group, the levels of total iron ions and ROS, the expression level of mitochondrial superoxide, the opening degree of MPTP, protein and its mRNA expressions of CypD as well as protein expressions of TfR1 and MCU were increased or up-regulated significantly (P<0.01); however, GSH content, mitochondrial membrane potential, protein and mRNA expressions of GPX4, and protein expressions of FTH1, ANT and CytC were decreased or down-regulated significantly (P<0.01). Compared with the si-GPX4 group, the cells in the DXQ-M, DXQ-H groups showed a general improvement in the above quantitative indicators (P<0.01 or P<0.05). CONCLUSIONS DXQ can enhance antioxidant capacity by activating the GSH/GPX4 pathway, regulate the expressions of TfR1 and FTH1 protein to correct iron ion homeostasis, inhibit excessive opening of MPTP to improve mitochondrial function, and ultimately suppress microglial ferroptosis.

Hepatocellular carcinoma (HCC) is a lethal cancer with high morbidity rates worldwide. It is a major threat to public health in China, due to the combination of known and new risk factors, such as endemic hepatitis B virus (HBV), dietary aflatoxin exposure, and the occurrence of metabolic dysfunction-associated steatotic liver disease (MASLD). Although many methods for surveillance and multimodal therapies, such as surgery, local ablation, transarterial therapy, and new systemic agents, have been available, the survival rates of HCC remains poor. They have very limited durable responses, long post-treatment recurrence rates, and high resistance to treatment. This reflects an imperfect picture of the biological cause of the disease and a need for new mechanistic or targeted techniques. A significant characteristic of HCC, in common with other aggressive cancers, is the presence of reprogrammed, hyperactive cell metabolism. Tumor cells hijack metabolic pathways to promote their uncontrolled growth, stress survival, invasion and metastasis. While classical mechanisms such as the Warburg effect, lipid metabolism and glutamine utilization have been understood, the lysosome, which was once viewed as a static “waste disposal unit” to remove old organelles and proteins, is instead a dynamic signaling and metabolic core. The lysosomes incorporate nutrients, energy and stress signals by master regulators such as mTORC1 (activated on its surface) that balance anabolic growth and catabolic recycling to the cellular demands. In HCC, lysosomes are not passive, but are highly active and dysregulated. HCC cells upregulate lysosomes, which scavenge intracellular components via enhanced autophagy and engulf extracellular proteins via macropinocytosis, crucial for survival in the nutrient-poor, hypoxic tumor microenvironment. In addition to metabolism, lysosomes exhibit pro-invasive functions by secreting hydrolases to remodel the extracellular matrix, promote angiogenesis, and suppress stromal immune cells to foster a pro-tumor microenvironment. In a clinical context, lysosomes play an important role in therapeutic resistance: they sequester and inactivate chemotherapeutics via lysosomal sequestration, and enhanced autophagic flux protects the cell from therapy-induced damage, contributing to relapse, as lysosomal dysfunction is a key cause of treatment failure. This makes lysosomes promising yet challenging therapeutic targets in HCC. Recent preclinical and early clinical studies investigate multiple strategies to exploit the susceptibility of lysosomes: lysosome-specific agents, alkalinizing the lysosome lumen or inducing membrane permeabilization and lysosome-dependent cell death; pharmacological inhibition of key lysosomal enzymes or autophagy to impair nutrient recycling and stress adaptation; smart nanotherapeutic agents or antibody-drug conjugates, specifically activated in the acidic lysosomal environment or utilizing lysosomal pathways for efficient intracellular drug release; and combination strategies of lysosome-targeting agents with tyrosine kinase inhibitors or immunotherapy to overcome resistance and achieve synergistic antitumor effects. In summary, our review systematically presents the role of lysosomes in HCC, from metabolic reprogramming and microenvironmental adaptation to therapeutic resistance. By synthesizing the latest mechanistic insights and preclinical advances, this review highlights the indispensable role of lysosomes in the complex HCC biological network, emphasizing that an in-depth understanding of this dynamic organelle holds great promise for developing innovative, targeted therapies, offering new hope for improving the poor prognosis of global HCC patients.

ObjectiveTo investigate the feasibility, safety, and efficacy of surgery-assisted transjugular intrahepatic portosystemic shunt (SA-TIPS) in the treatment of portal hypertension comorbid with complex portal vein thrombosis, including cavernous transformation of the portal vein (CTPV). MethodsAn analysis was performed for the data of 36 patients with portal hypertension and complex portal vein thrombosis who underwent SA-TIPS in Beijing Shijitan Hospital, Capital Medical University, from November 2023 to January 2025, including general status, technical data of the surgical process (surgical success rate, puncture times, time of operation, the number of stents used, and the length of shunt), perioperative complications, and surgical recovery. The change in portal pressure gradient (PPG) after shunt was compared, and the rate of reaching the standard for PPG reduction was calculated, as well as stent patency rate within 1 week after surgery. The paired samples t-test was used for comparison of continuous data between two groups. ResultsAmong the 36 patients, 34 (94.4%) underwent SA-TIPS successfully. The incidence rate of perioperative complications was 16.7% (6/36), including 3 cases of thoraco-abdominal hemorrhage, 2 cases of intraoperative arrhythmia, and 1 case of incision infection. There was a significant reduction in PPG after SA-TIPS (t=19.85, P<0.01), and the patients achieving a ≥50% reduction in PPG accounted for 76.5% (26/34). Imaging reexamination within 1 week showed a shunt patency rate of 100%. ConclusionSA-TIPS has a high technical success rate, a favorable safety profile, and good efficacy in the treatment of portal hypertension comorbid with complex portal vein thrombosis (including CTPV), and therefore, it holds promise for clinical application.

Objective To investigate the influencing factors of stroke patients with hypertension and their compliance with antihypertensive drugs, and to provide targeted intervention measures for stroke prevention in hypertensive patients. Methods Using the method of multi-stage cluster sampling, a total of 59,434 permanent residents aged 40 and above were selected from 48 monitoring sites in 9 cities of Hebei Province from December 2019 to December 2020. Unconditional logistic regression analysis was used to explore the influencing factors of stroke complicated with hypertension and the compliance of patients with antihypertensive drugs. Results Among the 59 434 subjects, the prevalence rate of stroke was 4.33% and the prevalence rate of stroke complicated with hypertension was 82.47%. The results of univariate analysis showed that the proportion of women, rural areas, dyslipidemia, diabetes, obesity, and people with family history of stroke was higher in stroke patients with hypertension, and the difference was statistically significant (P<0.05). Multivariate logistic regression analysis showed that rural areas, dyslipidemia, diabetes, obesity, and family history of stroke significantly increased the risk of stroke, and the OR (95%CI) values were 1.29 (1.03-1.62), 1.39 (1.12-1.72), 1.58 (1.25-1.99), 1.61 (1.22-2.12) and 1.60 (1.26-2.04), respectively. Among stroke patients with hypertension, 92.71% of patients took antihypertensive drugs. It was found that women's compliance with antihypertensive drugs was good, with an OR (95%CI) value of 1.46 (1.01-2.09). Conclusion The prevalence rate of stroke complicated with hypertension is high in people aged 40 and above in Hebei Province. Hypertensive people should lower blood lipids, control blood glucose, and lose weight as soon as possible to prevent the occurrence of stroke.
5.Professor WEI Zixiao's Experience in Differentiating and Treating Diabetes Mellitus Complicated with Urinary Tract Infection from Taiyin (太阴) and Shaoyin (少阴)
Journal of Traditional Chinese Medicine 2026;67(13):1378-1382
This article summarizes professor WEI Zixiao's clinical experience in the differentiation and treatment of diabetes mellitus complicated with urinary tract infection from the perspective of taiyin (太阴) and shaoyin (少阴). Professor WEI takes taiyin and shaoyin in the six meridians as the core differentiation framework, and puts forward that the core pathogenesis lies in deficiency of both the spleen and kidney, and the dysfunction of qi transformation as the root, and damp-heat pouring downward as the branch. It is held that xiaoke (wasting-thirst, 消渴) and strangury originate from the same pathogenesis yet present distinct clinical manifestations. Chronic cases are mostly characterized by deficiency-excess complex, lingering and difficult to heal. In clinical practice, the disease is condensed into four syndromes, taiyin syndrome, shaoyin cold-transformation syndrome, shaoyin heat-transformation syndrome, and concurrent taiyin and shaoyin syndrome. The key therapeutic principle is to restore the transportation function of the taiyin (spleen) and to enhance the qi-transformation function of the shaoyin. The corresponding methods include tonifying the middle and replenishing qi, warming the kidney and transforming qi, nourishing yin and relieving strangury, as well as strengthening healthy qi and relieving strangury. Representative formulas include Buzhong Yiqi Decoction (补中益气汤), Jisheng Shenqi Pill (济生肾气丸), Zhibai Dihuang Pill (知柏地黄丸) combined with Zhuling Decoction (猪苓汤), and Buzhong Yiqi Decoction combined with Jisheng Shenqi Pill, all with appropriate modifications. Bitter-cold medicinals are used cautiously, with emphasis on strengthening healthy qi and addressing both the root and the branch.

Objective:
To evaluate the feasibility of dynamic contrast-enhanced MRI (DCE-MRI) in differentiating tumor deposits (TDs) from metastatic lymph nodes (MLNs) in rectal cancer.
Materials and Methods:
A retrospective analysis was conducted on 70 patients with rectal cancer, including 168 lesions (70 TDs and 98 MLNs confirmed by histopathology), who underwent pretreatment MRI and subsequent surgery between March 2019 and December 2022. The morphological characteristics of TDs and MLNs, along with quantitative parameters derived from DCE-MRI (K trans , kep, and v e) and DWI (ADCmin, ADCmax, and ADCmean), were analyzed and compared between the two groups.Multivariable binary logistic regression and receiver operating characteristic (ROC) curve analyses were performed to assess the diagnostic performance of significant individual quantitative parameters and combined parameters in distinguishing TDs from MLNs.
Results:
All morphological features, including size, shape, border, and signal intensity, as well as all DCE-MRI parameters showed significant differences between TDs and MLNs (all P < 0.05). However, ADC values did not demonstrate significant differences (all P > 0.05). Among the single quantitative parameters, v e had the highest diagnostic accuracy, with an area under the ROC curve (AUC) of 0.772 for distinguishing TDs from MLNs. A multivariable logistic regression model incorporating short axis, border, v e, and ADC mean improved diagnostic performance, achieving an AUC of 0.833 (P = 0.027).
Conclusion
The combination of morphological features, DCE-MRI parameters, and ADC values can effectively aid in the preoperative differentiation of TDs from MLNs in rectal cancer.

OBJECTIVE To establish a clinical comprehensive evaluation framework for direct oral anticoagulants (DOACs) in the prevention of cancer-associated venous thromboembolism (CAVTE), providing a methodological reference for the rational prevention and treatment of CAVTE as well as for the formulation and adjustment of macro-management strategies for anticoagulant drugs. METHODS Through literature retrieval, evaluation indicators were collected and organized to establish a preliminary indicator pool. The selection of evaluation indicators was carried out through two rounds of Delphi surveys using average score of indicator importance≥3.5 and a coefficient of variation (CV) <0.25 as the screening criteria. Analytic hierarchy process (AHP) was employed to finalize the indicator weights. RESULTS The authority levels (C)r of the two rounds of expert consultations were 0.877 and 0.943, with CV of 0.24 and 0.18, respectively. The Kendall concordance coefficients were 0.331 and 0.535 (P<0.05). After expert validation, six primary indicators and forty-six secondary indicators were finalized for inclusion in the evaluation framework. The primary indicators and their weightings, ranked in descending order, were as follows:“ effectiveness” (38.86%), “safety” (38.86%),“ cost-effectiveness” (10.67%),“ accessibility” (5.51%),“ suitability” (3.48%), and “innovation” (2.64%). The secondary indicators exhibited a weight range from 0.02% to 20.25%, with the top five secondary indicators being:“ incidence of intracranial hemorrhage” (20.25%), “reduction in all-cause mortality” (15.29%), “decrease in the incidence of pulmonary embolism” (8.82%), “reduction in the incidence of deep vein thrombosis” (7.25%), and “drug contraindications” (4.74%). CONCLUSIONS This study has established an authoritative, scientific, and reliable comprehensive clinical evaluation framework for the use of DOACs in the prevention of CAVTE.

Background:
s/Aims: Sarcomatoid hepatocellular carcinoma (HCC) is a rare histological subtype of HCC characterized by extremely poor prognosis; however, its molecular characterization has not been elucidated.
Methods:
In this study, we conducted an integrated multiomics study of whole-exome sequencing, RNA-seq, spatial transcriptome, and immunohistochemical analyses of 28 paired sarcomatoid tumor components and conventional HCC components from 10 patients with sarcomatoid HCC, in order to identify frequently altered genes, infer the tumor subclonal architectures, track the genomic evolution, and delineate the transcriptional characteristics of sarcomatoid HCCs.
Results:
Our results showed that the sarcomatoid HCCs had poor prognosis. The sarcomatoid tumor components and the conventional HCC components were derived from common ancestors, mostly accessing similar mutational processes. Clonal phylogenies demonstrated branched tumor evolution during sarcomatoid HCC development and progression. TP53 mutation commonly occurred at tumor initiation, whereas ARID2 mutation often occurred later. Transcriptome analyses revealed the epithelial–mesenchymal transition (EMT) and hypoxic phenotype in sarcomatoid tumor components, which were confirmed by immunohistochemical staining. Moreover, we identified ARID2 mutations in 70% (7/10) of patients with sarcomatoid HCC but only 1–5% of patients with non-sarcomatoid HCC. Biofunctional investigations revealed that inactivating mutation of ARID2 contributes to HCC growth and metastasis and induces EMT in a hypoxic microenvironment.
Conclusions
We offer a comprehensive description of the molecular basis for sarcomatoid HCC, and identify genomic alteration (ARID2 mutation) together with the tumor microenvironment (hypoxic microenvironment), that may contribute to the formation of the sarcomatoid tumor component through EMT, leading to sarcomatoid HCC development and progression.
